Specification forming part oi' Leiters Patent No. 97,509, dated December7, 1869.

.T0 al?, whom t may concern Be it-known that I, DnNNIs HENRY GrinnsoN,of San Leandro, Alameda county, State of California, have invented acertain new and Improved Gang-Plow, and I do hereby declare that thefollowing is afull, clear, and eXact description of the same, referencebeing had to the accompanying drawings and figures and letters ofreference marked thereon, making a part of this specification, in which-Figure lis a side view. Fig. 2 is a plan. Figs. 3 and l are detaildrawings of the adjustable axle.

To enable others skilled in the art to make and use my invention7 I willproceed to describe its construction and operation as follows:

To my plow-beams A A, I attach the plowpoints B B, in the ordinary way,by bolts and braces, and no especial peculiarity is found in shape,construction, or manner of attachment of these plow-points.

My plow-beams A A are simply two beams of wood, connected by across-piece and tiebolt, as shown at C, one of these beamsthe onecarryingthe rear plow-point-being slightly longer than the other, asshown in the drawings. These beams A A are attached by the fulcrum-boltD to the draft-pole E at a point considerably in advance of the axle ofthe plow-wheels. The draft-pole E is a hat timber in width correspondingto distance between the beams A A; but from a point a few inches beyondwhere the fulcrum bolt E passes through it, it is fashioned into a roundpole, as the common wagon-pole. rlhis draft-pole is firmly bolted to theaxle-tree or axle-beam The roller -shaft (so called) G, with itsattached links H, arm I, and hand-lever K, though not new in principle,I have endeavored to simplify in its application. Upon each.plow-beam I provide bearings, of either hard wood or iron, with suitablecaps to cover them, and in these bearings I rest my roller-shaft. Midwaybetween the bearings the rigid arm I projects from the shaft, and by thelinks H I-I is connected with the fulcrum-eyebolt L-:a j ointboltsecuring the connectionwhich fulcrumbolt L is set at near the end of thedraft-pole E. The hand-lever K is secured by one bolt to the flat partof the roller-shaft G, which is -end of the roller-shaft.

bent at right angle tothe shaft and parallel to the rigid arm I, forminga short'arm on the A stout spring,` M, is attached by a strap at theextremity of this short arm, and this spring M, bearing against thehand-lever, serves to keep it in close contact with the notched 'bar N,which notched bar, holding the hand-lever at any desired point throughit, holds in various position of elevation the plow-beams in connectiontherewith. a bolt to the back standard of the seat, and upon the beamfulcrum-bolt I), as shown in Fig. l. A guard-bar, O, swinging in staplesset in the standards or supports of the drivers seat, serves, when swungout, to fend off the hand-lever from engaging with the notched barduring the operation ofplowing-a device in common use and of well-knownconstruction. rlhe drivers seat has no especial peculiarity, beingsimply a seat supported on four light standards, the two back standardsbeing bolted to the axle-tree and the front ones rest on thefulcrum-bolt I), the foot-board being supported on projecting beamssecured to the standards of the seat, in manner clearly shown in Eig. l.The axles for each plowwheel are separate, and are secured to the woodenaxle-tree by strap-bolts, as at P I), and by the two bolts in theeenter,which also serve in securing the draft-pole to the axle-beam oraxle-tree. One of these axles is fashionedin a peculiar manner, so as toadmit of adjusting the height of the wheel to provide for theaccommodation ofthe plow, and to keep it level when operating onhillsides or sloping grounda .matter understood by those acquainted inthe art. The manner in whichthis axle is constructed is as follows: Thepartwhich is secured to the axle-tree is bent upward at a right anglewith the axis of the wheel, andthis upturned part R is provided with anelongated slot. rIhe axle proper, upon which the wheel revolves, is ashort piece of iron, consisting of ajournal for the wheel and a shortshank with thread cut on and nut on end, between the shank and thejournal, a collar or shoulder intervening, which separat-es the hub ofthe wheel from the continuing part ot the axle. The short shank of theaxle proper is passed through the slot in the main part ofthe Thenotched bar N is secured by"` axle, and byserewing up the nut :it isfirmly maintained in anyposition in which it may be set inthe slot, andin this Way is the height of the Wheel adjusted, the limitation beingdue to the height or length given to the slot.

The operation of my plow is substantially similar to other gang plows.Horses are hitched to the draft-pole E, and drag the plows through thesoil. The driver, seated upon his seat, controls the horses, and, bymeans of the hand-lever at his side, may raise or lower the plow-pointsas maybe required in the operation of plowing, the whole of the machinebeing carried forward and supported upon the wheels, as clearly shown inthe figures of the drawings.

I do not ela'nn as new any of the separate parts of my invention, forthese parts, I am aware, are to be found in other gang-plows; butinasmuch as I have invented a peculiar combination of these parts, whichas a whole I claim is new and improved, I desire to be secured thereinby Letters Patent of the United States. I will here specifically setforth that rIhe combination and arrangement of the parts of my gangplow, as herein described, this combination and arrangement consistingin attaching the draft-pole E rigidly to the non-extensible axle of thecarrying-Wheels, the plow-beams being hung on the fulcrumbolt D, whichpasses through the forward standards of the drivers seat, and thedraftpole in advance of the axle, and which plowbeams are operated by aroller-shaft and attachments, as shown, the whole of the parts beingcombined and arranged together in manner substantially as described, andfor the purposes as set forth.
